You can epoxy over stained wood. Sanding your surface before applying the epoxy will create a better bond, but if you decide not to sand, you still need to clean the surface and repair any dents or scratches.
If you do decide to sand, make sure that you are removing all the stains while not going through the layers of wood
Can you epoxy over stain?
You can epoxy over the stain. The stain will change the color of the epoxy, but you can add color to your epoxy as well.
Epoxies aren’t always used for repairs, either. Sometimes people create interesting effects by mixing different types of epoxies and adding color or metallic powder to them.
This works especially well with transparent or translucent finishes—you can see layers of colors that have been mixed together in an interesting way!
If you want to keep your stained wood looking exactly how it does now, then use polyurethane instead of epoxy when you apply it to your project.

How long after stain can I epoxy?
So, how long after applying a stain can you epoxy? It depends on the type of stain. If you are using an oil-based stain, you must wait at least 48 hours (2 days) before applying epoxy. This allows the oil to completely weather off and for all of the excesses to dry.
Water-based stains are not as difficult to work with because they do not contain any solvents that would interfere with your epoxy’s bond strength or ability to adhere properly. With water-based stains, it is recommended that you wait at least 12 hours after application before proceeding with your project (1 day).
Will epoxy stick to varnished wood?
As a rule, you should sand and clean the surface of your project before applying any finish. But if you’ve already varnished your wood, you can still apply epoxy over it.
Just make sure that the varnish is dry before applying epoxy so that the sealer doesn’t get trapped between layers. Otherwise, it could result in an uneven application or bubbling during curing time.
Once cured, you’ll have a glossy finish on top of your old coat of varnish—but don’t worry! You can sand off whatever amount of material that needs to come off via hand or power sander when preparing for another layer of epoxy down the line (assuming there’s enough depth).
Do you stain wood before or after epoxy?
When you’re applying epoxy to stained wood, it’s best to apply the stain prior to the epoxy. This is because stains will not adhere as well over epoxy, and they can sometimes peel off or crack if applied over a cured epoxy.
If you’re planning on using varnish, paint, sealant, or water-based stain on your project first (as opposed to just using polyurethane), then go ahead and apply that before applying your polyurethane coating.
When applying any of these coatings onto stained wood, try not to let them dry too long before adding a second coat in order to avoid uneven coloring from being left behind.
Do you need to seal wood before epoxy?
You don’t need to seal your wood before epoxy, but you do need to prepare it. First, make sure the wood is clean and dry (water in your wood’s pores will cause the epoxy to peel).
Then sand down any rough areas with fine grit sandpaper. Vacuum away any dust from sanding.
Next, de-gloss your piece of furniture so that your glue blends with what’s already there instead of shining through like a brand new layer around every edge or corner.
You can use a paint stripper if you want something that blends quickly or use some acetone on a rag instead if you’re going for something slower and more natural looking (which may be an option depending on what kind of texture is already present).
Can you pour epoxy over water-based stain?
It depends on what you’re using.
You can pour epoxy over a water-based stain, but it’s not recommended. This type of paint is typically meant to be washed off with water, so it doesn’t have a very strong bond to the wood.
Epoxy will stick to it, but if you need to remove your project at any point in the future, there’s no guarantee that all of the water-based stains will be removed from underneath.
For this reason, many people choose not to pour epoxy over any kind of paint or stain at all (unless you plan on painting over what you’ve just done—more on that below).
But that doesn’t mean there aren’t other options! If you want something more permanent than shellac or lacquer and don’t mind risking some early failure with your epoxy job, go ahead and try pouring over oil-based or shellac-based finishes as well as lacquer (as long as they’re dry).
You’ll still want to use an exterior-grade resin-like Castin Craftsman Clear or Rustoleum Rubberized Clearcoat when doing so because they’re more resistant to chemicals than interior varieties like BIN Shellac Sealer which could interfere with curing times while also being prone to peeling off later due to humidity changes throughout winter months
How do you prepare wood for epoxy?
If you want to use epoxy over-stained, you’ll need to prep your surface.
- Remove any paint or varnish with a sander and clean it with a cleaner
- Fill any gaps or cracks with wood filler, then sand the wood again before applying primer and conditioner if it’s bare wood that hasn’t been sealed yet.
- Apply one coat of primer before applying two coats of epoxy resin over the entire surface area of your project.
Can you put polyurethane under epoxy?
Polyurethane is a hard finish that’s applied over wood and other surfaces. It usually comes in a can, which is why it’s referred to as a “spray-on” finish.
Polyurethane provides UV protection and makes surfaces more resistant to scratches, dents, and stains than other finishes like varnish or lacquer. Once dry, it’s also highly durable—providing added protection against heat and water damage.
Although it may seem counterintuitive at first glance, the answer is yes! You can apply both epoxy paste and polyurethane underneath your project if you want the best of both worlds: the durability of epoxy without sacrificing any beauty of your finished product!
Conclusion
That’s it! We hope you enjoyed this guide on epoxy resin and stained wood. Keep in mind that epoxy resin can be used for a wide variety of projects, so don’t be afraid to experiment with it.
